`-exact description thereof, which will enable others skilled in the art to'make and use the same, reference being had to the accompanying drawings. forming part of this specification.`

This invention relates to improvements in machines for cultivating corn and other vege. tables planted in rows.v

It consists, first, in an arrangement, upon a truck of two or more wheels, of two or more hoes or spades, moving to and from the row as the machine moves along by motion derived from the truclmvheels, so as to scrape or hoe the earth up to the roots ofthe plants, the said spades or hoes being raised above the ground when moving away from the plants, and down into contact with it when moving up toward them.

The invention consists, secondly, in the conibination, with the said hoes or spades, of a shield for gathering the tops ot' the plants and holding them up, so as not to be covered or injured by the hoes 5 and the invention consists, thirdly, in the combination, with the said holes, of cultivators arranged to operate in the ordinary way, and provided with means for raising and lowering tl1e1n; also, for guiding one pair of the said cultivators which run close to the plants laterally by the feet; and it consists, fou-rthly, in certain arrangements of parts for working, guiding, and operating the spades and eultivators.

' Figure l represents a longitudinal sectional elevation of my improved' machine. Fig. 2 represents a plan view of the saine, and Fig. 3 represents a rear end elevation of the same.

A represents a suitable truck-frame, mounted on two wheels, B, and short separate axles C. The said frame is arranged with a wide and high clear space, D, at the center, so that it may be drawn along the row, with onewheel on each side of it, without injuring the plants. At the rear end of this frame, and on each side of the space D, I arrange one or more spades or hoes, E, fixed upon bars F, mounted on wrist-pins G o1" cranks or disks H of shafts I, journaled on the frame A at right angles to the axles, and deriving motion therefrom by gear-wheels K, so that the hoes have a movement to and from the row ol" plants, the s aid hoes being down in Contact with the ground wllen'inoving toward them. The upperends otthese vbars F are confined against lateral moti on by passing through gai de-eyes ol" plates L; er other similar devices which will accomplish the purpose may be used. The to-andfro rand rising-and-i'alling movement is imparted to these spades'or hoes by the turning of the crank-shafts, as will be readily understood, and in moving toward the rows they scrape the soil up to the roots of the plants, distributing it evenly around them. Chains M are connected to the bars F, and rising up over pulleys N pivoted to the frame, and ar ranged to be tu rned forward to draw the spades upward and support them above the ground by beingheld in the said forward vpositions by spring-catches l) at the top of the frame.

Q is a shield or guard composed of curved bars of wire, sheet nieta-l, or other suitable substance connected to other parallel bars, R, suspended from the bars S, pivoted to the front ot' the frame A at T, so that the lower ends are drawn along the ground in a way to gather the side projecting ,branches of the plants and draw them inward just in advance ofthe spades to prevent injury to them by the side spades, These bars S also support the stocks U of a pair of cultivators, V, of ordinary construe-- tion, in advance of the shield and spades, one on each side of the row. The said stocks are connected together at the top by a bar, NV, Y

loosely jointed to them, so as to admit them .to turn laterally on their pivot-joints Xand chains Y, connected to the tops of the-said stocks, pass over guide-pulleys to foottreadles Z, so arranged that the operator, sittingfon the seat' at Z', may vibrate the eultivators V. to or from the row of plants. The arms S are provided with other short arms, S', projecting at right angles from them horizontally, and toward the sides of the frame in advance of the eultivators V. To the outer ends of these arms are j ournaled the stocks V of other cultivators, V2, so as to oscilla-te on the said journals. These stocks V are connected by brace chains or rods W" to the frame A, which sustainsthe resistance encountered when being drawn along on the ground. `II represents another pair ofcult-ivators, the stocks of which are jointed to the fraineA atHi. flheir stocks have links or rods H connected to them near the bottoni, and to the bars S by bars or rods il, so that when the said bars are raised they 'will be also raised above the ground. These cultivators track between the cultivators V and V, andthe whole serve to work the ground thoroughly before the spades, so that the soil taken by them to deliver to the plants will be fresh and clean.

A is a rolleushaft arranged ltransverse] y on the top ofthe frameA and provided with arms B and chains C, connecting the said arms with the bars S.

D is a hand-lever connected to the shaft A for turning it to raise or lower the bars S, to which the cultivators and the guard Q are con'- nccted. This hand-lever may be turned on its `ioint with the shaft A', so as to be engaged under a clutch, E, for holding the bars S up above the ground when required for transporting the machine from place to place. gnardQis connected by a chain, Q, to ahook on the rear of the machine in a way to be sus` pcnded higher or lower, as required.

The wheels B are placedloosely on the axles, andhave clutches B'for gearing the axles to them to be turned by the said wheel. These clutches slide on the axles, and are moved by The' bent levers B, pivoted at- B, and connected by rods B5 to a handllever, l", pivoted to the frame, and arranged to move the said clutches in opposite directions simultaneously.

Having thus described my invention, I claim as new and desire to secure by Letters Patentsl. The combination, on a truck, of two or more hoes or spades, E E, arranged for operation by motion derived from the wheels o1' the truck, as herein 'shown and described.

2. The combination, with a pair of Spades or hoes, operating as described. of a guard or H. W. GLAPI?.
